(A) At the crossing of any roadway, the following minimum vertical clearances are required:
(1) Eighteen feet for communication cables, guy wires and secondary power wires below 750 volts.
(2) Twenty feet for voltages between 750 volts and 15,000 volts.
(3) Twenty-two feet for voltages between 15,000 volts and 50,000 volts.
(4) Twenty-one feet plus .4 inch/KV in excess of 50 KV for voltages between 50 KV and 470 KV.
(B) For longitudinal lines, the following minimum clearances will be required:
(1) Eighteen feet for communications cables, guy wires, and secondary power wires below 750 volts.
(2) Twenty feet for voltages between 750 volts and 15,000 volts.
(3) Twenty-two feet for voltages between 15,000 volts and 50,000 volts.
(4) Twenty-one feet plus .4 inch/KV in excess of 50 KV for voltages over 50 KV and up to 470 KV when allowed within county right-of-way.
(C) All clearances are absolute minimums based on worst case considerations of electrical conductor loading, physical conductor loading, and ambient conditions. The minimum vertical clearance is herein defined as the shortest vertical distance of the line over any location on the county right-of-way. Voltages are phase to ground.
(D) Consult the National Electric Safety Code ANSI-C2 for additional clearance information.
